Enthalpy of adsorption for physisorption is low and positive.
Open in App
Solution
The correct option is B False
The enthalpy of adsorption for physisorption is quite low, usually between 20- 40 kJ per mol.
This can be explained easily through the fact that the forces involved in physisorption are weak and hence the enthalpy difference would also be low accordingly and it is exothermic.
